Minimum continuous flow rate of variable frequency pump
Thread Content
Pumps operating at line frequency generally have a minimum continuous flow rate of 20–30%. But under variable-frequency operating conditions, how is the minimum continuous flow rate determined? For example, at the power frequency, the rated flow rate is 1000, with a minimum continuous flow rate of not less than 200. But what happens when an inverter is used? I would like to ask everyone for advice. . .
It is related to the design of the pump and its operational procedures; the main factors include the minimum net positive suction head, prevention of temperature increases, and preventing the pump from becoming empty
I mean simply the pump; aside from the process requirements, the minimum continuous flow rate of the pump can change after installing an inverter.
